The same functionality is already implemented in Django admin. I can add, modify, remove inlines and modify model instance as I want. I am wondering why should I use this

问题 I have a table inside a form, generated by a formset. In this case, my problem is to save all the items after one of them is modified, adding a new "virtual" column as the sum of other two (that is only generated when displaying the table, not saved). I tried different ways, but no one is working. Issues : This save is not working at all.
